Validación de KINOVEA como herramienta para el análisis de posturas en tareas sedentarias.

Abstract

The purpose of this paper is to validate the Kinovea software as a tool for the analysis of postures in sedentary tasks. In this case, we analyzed the postures of students and workers who, due to the pandemic caused by the SAR-CoV-2 virus, adopted the virtual mode both in their studies and in their work, so that their homes became their main working space. As a result of this, they present ailments caused by staying in non-ergonomic postures during their workdays. To determine the ergonomic risk, initially a group of volunteers participated in a survey. Then, to obtain data for validation, in the biomechanics laboratory of the Escuela Politécnica Nacional, these people imitated selected postures and movements in a controlled environment according to an experimental procedure. This whole process was monitored with two systems: the first is the set of cameras associated with Kinescan in the laboratory, and the second, with a mobile device to obtain a video that was later analysed with Kinovea software. From this, video graphic samples were obtained and analysed under the RULA ergonomic assessment method. Finally, the results determined that the software can be used to analyse postures quickly and reliably. Therefore, recommendations could be issued regarding the furniture used in sedentary tasks to avoid muscular damage that could lead to musculoskeletal disorders
